Delta8-fatty-acid_desaturase
Delta8-fatty-acid desaturase (EC 1.14.19.4, Delta8-sphingolipid desaturase, EFD1, BoDES8, SLD, Delta8 fatty acid desaturase, Delta8-desaturase) is an enzyme with systematic name phytosphinganine,hydrogen donor:oxygen Delta8-oxidoreductase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- phytosphinganine + reduced acceptor + O2 Delta8-phytosphingenine + acceptor + 2 H2O
This enzyme, which has been found mainly in plants, introduces a double bond at Delta8 of C18 and C20 fatty acids.
